AUTOMATIC PERFORATOR AND SCORER.

SPECIFICATION forming part of Letters Patent No. 729,633,11ated1une 2, 1903.

Appllcation filed June 12, 1901- To all whom, it may concern: v

Be it known that I, CARL J. MITTLER', a citizen of the United States, residing at Louis ville, Jefferson county, Kentucky, have invented certain new and useful Improvements in Automatic Perforators and Scorers, of which the following is a specification, reference being had to the accompanying drawings, wherein v Figure 1 is a side view of a device which includes my improvements, one side of the outer casing thereof being removed to show the perforating or scoring rule and its raisingplate, said rule being shown in its inner position of adjustment. Fig. 2 is a similar viewshowing the perforating or scoring rule in its outer position ready to perforate or score and also indicating the relation thereto of the means which acts onsaid elevating-plate to push the perforating or scoring rule to its outer position at a predetermined time in the operation of the press. Fig. 3 is a plan of said means referred to in Fig. 2. Fig. at is a view of the same looking thereat from a point at right angles to that from which it is viewed in Fig. 3. Fig. 5 is a side view of one end of the device with theperforating or scoring rule in its lowered position. Fig. (3 is a similar view with said rule pushed out into operative position.

The same letters of reference designate the same parts in the several views.

This invention relates to certain improvements in devices applicable to printingpresses by which the paper may be perforated or scored simultaneously with the printing thereof without liability of the inkingroller coming in contact with the perforating or scoring rule, thus obviating the necessity of two impressions and preventinglaceration of the inking-roller.

The invention consists in certain peculiarities in the construction of parts and-in certain novel combinations of elements, substantially as hereinafter described,- and particularly pointed out in the subjoined claims.

The frame of the device, which includes two side plates at a, is of a size and shape to contain the perforating or scoring rule I) and the plate 0, which is operated to project the rule 12 so that its scoring or perforating face has an inclined outer face.

Serial No. 64.342. (w man will score or perforate the paper. Said plate 0 and rule I) are mounted to' have longitudinal relative movement in the frame, and the engaging faces of the plate 0 and rule I) are each formed with alternate projections andrecesses, constituting cams, which are relatively such that during the'longitudinal relative movement aforesaid in one direction the rule b will be projected into operative position, and in the reverse direction said rule I) will be caused or permitted to return to its inner position within the frame, with its proj ections received within the recesses in said plate. This alternate outer and inner movement of the perforating or scoring rule must be properly timed with the printingand inking mechanism, respectively, of the press with which the device is being employed in order that the perforating or scoring will be made simultaneously with the imprint and the rule withdrawn prior to the passage of the inking-roller over it, and to this end the operation of the plate 0 is I controlled by the press. The means by which it is connected with the press and is thus controlled constitute important features of my invention and are preferably as follows: One end of the plate 0 is provided with a projection d, which A plate g has a groove into which extends an arm It, said arm being adj ustably secured at one end in said groove by suitable means, such as a thumbnut t, and having its non-secured end h bent to extend into the path of said projection (1, so as to engage the inclined surface of the latter when said arm d is brought in contact with it by the movement of the chase, (which carries the perforating or scoring mechanism. in addition to the type,) and thereby cause said longitudinal relative movement of plate 0 and 1 rule I) in one direction and cause the engaging surfaces thereof to project said rule into position to perforate or score. The plate g is adapted to be adj ustably secured to the cross-rod or gripper-rod of the press by the bolt j and nut j, which bolt extends through the elongated slot is in said plate. An indicator 6 is pivoted at its lower end, as indicated at e, to the projection (l and denotes where the arm h should rest. The projection d is of such weight as to return the plate 0 to its position v in which it causes or permits the perforating or scoring rule to recede to within the frame, thus avoiding the necessity of employing springs for this purpose. The ends of the rule are formed with slots f, into which project pins from the side a of the frame, whereby the rule is guided and limited in its movements.

The operation is as follows: The frame is secured in the chase alongside the type. The indicator e is adjusted pivotally, so as to denote by its impression on the receivingboard of the press Where the arm h-must rest, and the edge of said arm is adjusted to the level of the mark thus made and is secured in said position by the thumb-nut After the first impression has been made said indicator is turned out of the way. In the operation of the printing means toward the paper to be imprinted the projection (Z is engaged by the projection h and is thereby forced to protrude the perforating or scoring rule from the frame and into perforating or scoring position, and in the reverse movements of the parts said projections are disengaged from each other and the weight of said projection (Z is permitted to operate automatically on the plate 0 to permit said rule to recede within the frame, these operations being so timed that the perforating or scoring of the paper occurs simultaneously, or approximately so, with the printing thereof and the rule is withdrawn out of the path of the inking-roller prior to the passage of the latter over the type.

Having thus described the invention, what I believe to be new, and desire to secure by Letters Patent, is-

1. The combination with a perforating or scoring device for printing-presses, embracing a perforating or scoring rule and a plate, mounted to have longitudinal relative movement and having engaging faces formed so that during such longitudinal relative movement the rule will be caused to protrude and recede into and out of operative position, of means applied to the press for actuating said plate, said means including an adjustable arm, and an indicator carried by oneof the parts for determining the position to which said arm should be adjusted.

In a perforating or scoring device for pi'intingpresses, the combination of a frame, a perforating or scoring rule mounted therein and adapted to be projected therefrom, a rel atively movable plate in said frame, engaged with said rule; said rule and plate having their engaging surfaces relatively so formed that the perforating or scoring rule will be alternately projected into and withdrawn from operative position during longitudinal relative movement thereof, and means for causing said longitudinal relative movement, embracing a projection on the end of said plate adapted by its weight to actuate the same in one direction, and a projection from the press to-engage thefirst-mentioned projection and act in opposition to the weight thereof.

3. In a perforating or scoring device for printing-presses, the combination of a frame, 1 a perforating or scoring rule mounted therein embracing a projection on .the end of said 5' 5 plate adapted by its weight to actuatethe same in one direction, second projection, to r engage the first-mentioned projection and act in opposition to the weight thereof, means 7 carryingsaid second projection and adapted to be supported from the cross-rod or grippera rod of the press, and adjustable securing means for said second projection, by which its position relatively to the first projection."

may be adjusted.

4. In a perforating or scoring device for" printing-presses, the combination of a frame, a perforating orscoring rule mounted therein 7 and adapted to be projected therefrom, arel atively movable plate in said frame, engaged with said rule,said rule and plate having their engaging surfaces relatively so formed i r that the perforating or scoring rule will'be alternately projected into and withdrawn from operative position during longitudinal relative movement thereof, and means for causing said longitudinal relative movement, embracing means for operating the same in one direction, a plate having means by which it may be adjustably secured to the cross-rod or gripper-rod of the press, an arm adjustably mounted on said plate and having means for fixing it in adjusted position and a projection from said arm adapted to engage an end of the first-mentioned plate and actuate the same in opposition to its before-mentioned operating means.

5. In a perforating or scoring device, for printing-presses, the combination of a frame, a perforating orscoring rule mounted therein and adapted to be projected therefrom, a'plate in said frame, engaged with said rule and having longitudinalmovement relative thereto, said rule and plate having their engaging surfaces relatively so formed that the perforating or scoring rule will be alternately projected into and withdrawn from operative position during longitudinal relative movement thereof, means for causing said longitudinal relative movement, embracing a projection on the end of said plate adapted by its weight to actuate the same in one direction, a plate having means by which it maybe adj ustably secured to the cross-rod or gripperrod of the press, an arm adjustably mounted In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
